Background: Melanoma is the most serious form of skin cancer and it has the highest rate of growth among different types of cancers. Ursolic acid (UA), a natural pentacyclic triterpenoid, is a major bioactive compound in several traditional medicinal plants including pomegranate (Punica granatum L.) flower. UA has very important biological and pharmacological functions. Objective: In this study...
Melanoma is the most dangerous skin cancer due to its highly metastatic potential and resistance to chemotherapy. Currently, there is no effective treatment for melanoma once it is progressed to metastatic stage. Therefore, further study to elucidate the molecular mechanism underlying the metastasis of melanoma cells is urgently required for the improvement of melanoma treatment. In the present...
In the present study, we observed a marked variation in the expression of PKCα and PKCδ isotypes in B16F10 melanoma tumor cells compared to the normal melanocytes. Interestingly, the tumor instructed expression or genetically manipulated overexpression of PKCα isotype resulted in enhanced G1 to S transition. This in turn promoted cellular proliferation by activating PLD1 expression and subseque...
Purpose We investigated the application of contrast-enhanced ultrasound (CEUS) to quantify vascular perfusion in two animal models of choroidal melanoma. Methods B16F10 and choroidal melanoma cell line (OCM1) melanoma xenografts were implanted into the cyclodialysis cleft of rabbits' right eyes. Fundus photography, indocyanine green angiography (ICGA), B-mode ultrasound, and CEUS were used to...
Previosuly, we reported the cytotoxic effect of colloidal silver (AgC) on MCF-7 breast cancer cell line. However, there is scarce information on its antitumor potential. The aim of this study was to evaluate the anti-tumoral activity of colloidal silver (AgC) or silver nanoparticles (AgNPs) in a B16F10 melanoma mice model. In vitro, B16F10 cells were treated with different concentrations of AgC...
objective: recent evidences suggest that tumors arise from a small subpopulation of cells, the cancer stem cells (cscs) or tumor initiating cells. cscs are able to resist the conventional methods of cancer therapy due to existence of abc transporters on their surface. this leads to csc resistance and maintenance resulting in post-treatment relapse and metastasis. therefore, precise identificati...
Laminin is a large multidomain protein with diverse biological activities. We previously demonstrated that intact laminin as well as an A chain synthetic peptide (LamA2091-2108) stimulate tissue plasminogen activator (t-PA)-catalyzed plasminogen activation. Here we report that LamA2091-2108 increases t-PA production by the highly metastatic murine melanoma cell line B16F10, with no effect on th...
Photosensitizer-free vaccination strategy can be accompanied by delivery of nanoadjuvants. B16F10 melanoma cells show a photothermal effect under irradiation near-infrared light. The nanoadjuvant, with imiquimod in amphiphilic peptide-based micelles, induces dendritic cell maturation. Near-infrared-irradiated and nanoadjuvant-treated group prevents lung metastasis B16F10. phototherapy peptide m...
Merlin, the protein product of the neurofibromatosis type 2 gene (NF2) acts as a tumor suppressor in mice and humans. In this study, melanoma B16F10 cells were engineered to overexpress the NF2 gene by establishing stable transductants. A cell line overexpressing Merlin (B16F10-M) was generated. When compared to the parental cells, the B16F10-M cells demonstrated differences in their cell surfa...
Vitamin C has inconsistent effects on malignant tumor cells, which vary from growth stimulation to apoptosis induction. It is well known that melanoma cells are more susceptible to vitamin C than any other tumor cells, but the precise mechanism remains to be elucidated. In the present study, the proliferation of B16F10 melanoma cells was suppressed by vitamin C, which induced growth arrest in a...
